I am attempting to get my late fathers T running by spring to give my 81 yo mom a ride in it. I got it running a couple years ago, but the carb needs rebuilding or replacing. I had to hold the adjustment knob to keep it steady but even at that, I know the needle is worn real bad. Iíve made a feeble attempt to find a rebuilt carb but really didnít try as hard as I should. Any direction anyone can point me to find another one would be greatly appreciated. Hereís a couple pictures of it. Any idea what kind it is.? Thanks

Update: Thank you for the responses. I pulled the carb and found a tag on it that says Kingston L4 but the adjustment on the top appears to be round with two holes and off a Holley 4550. Is this a usable combination? Will the car run normally if I rebuild it with this set up? If not, what should I replace it with for this engine? I did by the way look up the serial number on the block and identified it as between July 1917 and July 1918

The "correct" carburetors for 1917-1918 are Holley G and Kingston L-2, if you care about that. My 1915 has an incorrect Ford NH until I get around to rebuilding a G for it. The NH (Ford or Holley) is plentiful (cheap) and easily rebuilt. The MTFCA carburetor book tells you what to do.

Here are some pictures of an L2 on the left and L4 on the right. The threaded sections on the Kingston and Holley needles are in different places/lengths plus the Kingston needles are longer. The Holley 4550 and G needles interchange while the 4450 or S for 1913 is different. The Kingston needles from the 4 ball to the L4 will all interchange but the top styles are different by year.

Thank you so much for going to all that trouble to help me understand and the information and pictures. Your explanation and differences of the adjustment needles certainly makes sense and why Iím having the issues Iím experiencing. I now know what to do.
